In a theoretically perfect combustion, carbon dioxide, water and nitrogen are the end products.
In reality, the incomplete combustion of diesel fuel results in emissions that include oxides of nitrogen (NOx), carbon monoxide (CO), carbon dioxide (CO2), water (H2O) and unburned hydrocarbons (HC). There are also unburned carbon particles, as well as engine oils, soot and ash particulates, which are known as particulate matter (PM).
The diesel particulate matter (DPM) id the visible cloud of black smoke that appears from engine start-up and continues to appear when engine is running.
Passive regeneration accurse between 550°C and 600°C degrees. The engine needs to run at these temperatures for a minimum of 60% of engine working time to ensure regeneration, If this regeneration does not occur, there is a build-up of soot which will lead to the backpressure in the exhaust system to rise.
If this situation occurs the DPF filter will need to be removed from the machine and baked at 800°C for 8 hours, all depending on the level of clogging that has accrued. Air is then used to pulse through the filter to remove the remaining ash.
The baking of the DPF filter need to be conducted by Rush Exhaust & Rush Enterprises for the interim, on an exchange base, to reduce costs. Were a retrofit unit can be used.
For every 10 DPF filter in used a recommended 3 Units should be on standby to eliminate any down time, in the production line
